The EIA released the latest edition of their Electric Power Monthly on January 24th, with data for November 2017. The table above shows the percentage contribution of the main fuel sources to two decimal places for the last two months and the year 2017 to date.

EIA provides estimates of proved reserves based on information from the E&Ps on form EIA-23 for crude only, and also shows the categories for changes (discoveries, production, revisions etc.). This data with updates for 2016 has been due since November but so far has been twice delayed. BOEM make their own estimates for 2P (i.e. proved and probable) based on strict adherence to SEC/SPE rules (i.e. the reserve must be on production or be expected to be produced within five years). I think this usually comes out in May. In the absence of the latest EIA numbers I’ve presented the 2015 numbers with adjustments for subsequent production. There will be revisions and additional discoveries to include once the actual data is available though I think fairly small, especially for gas, but it will be interesting to see.
Despite excluding probable reserves and counting crude only, the EIA estimates have recently exceeded those from BOEM. It looks like a lot of the probable reserves were converted to proved through positive revisions in the period 2008 to 2011; i.e. possibly due to some price increases then, but also immediately following the SEC rule changes to exclude reserves without firm development plans, which may or may not be coincidental: the E&Ps may be less strict on applying the SEC/SPE rule, which they are allowed to do for large, long term projects. The BOEM estimates are pretty much flat over recent years as additions (which then become backdated “discoveries”) from new projects going through FID balance production, whereas EIA estimates are declining with revisions recently zero to negative.

From Dec 2016 to Dec 2017 US Tight oil output has increased by 975 kb/d based on US tight oil output data from the EIA.
For the entire US we only have EIA monthly output estimates through Oct 2017. Over the Dec 2016 to Oct 2017 period US output has increased by 866 kb/d and the OLS trend has a slope of 821 kb/d.
Note that the 866 kb/d increase in US output over 10 months would be a 1040 kb/d increase over a 12 month period.
Most of the increase in US output has been from increased LTO output. The forecasts by several agencies (EIA, IEA, and OPEC) of more than a 1000 kb/d increase in US output in 2018 may assume that the recently increased oil price level will lead to increased investment in the oil sector.
Much of the increase in LTO output has been in the Permian basin and several factors may slow down the recent rapid growth. Among these are limited fracking crews, inadequate pipeline capacity for natural gas, which will limit output as flaring limits are reached, and potential water shortages.
Longer term the various LTO plays will run out of space to drill more wells in the tier one areas (the so-called sweet-spots) and this will limit the rate of increase within 2 or 3 years. It is likely that the Eagle Ford is close to this point, the Bakken might reach that point by 2019, and the Permian basin perhaps by 2021.
For US C+C output, I expect about a 600+/-100 kb/d increase in 2018.
